Worst shipping company i ve ever come across! avoid it at all cost. I placed an order from their app and then realized it was the wrong item, i wanted to cancel my item while the item was still processing before it got confirmed, i called, emailed but literally no answer nothing! are they even in business ? i mean a business can t just be that busy! if you re so busy get more people working in customer service! it s been a week and no response!
